How long does ithe light take to reach earth from the suns
which is 1.5^10 11 m (power 11) away?

Answer 1

Answer:

Hey mate!! Let me help you for this question.....

Given:

=>Speed of light =  3 ×  $10^{8}$ m/s

=> Distance of Earth from Sun = 1.5 × $10^{11}$ or 15 × $10^{10}$m

Solution:

We know,

Distance = Speed × Time

=> Time =  $\frac{Distance}{Speed}$

=> Time = $\frac{1500000000000}{300000000000}$ (Sorry there is no multiplication symbol in laptop )

=> Time = 500 sec

Hope you understood the answer....
